Aquaculture Production


 

 

1.0. Export production through aquaculture:

Export oriented aquaculture production continues to increase year over the year and the increased production contributed significantly for the sea food exports from the country. Aquaculture production has increased to 5,00,581 MT during 2015-16 with an increase of 15.19% over the production of 4,34,558 MT during the previous year 2014-15.

Production of the Pacific white shrimp (Litopenaeus vannamei) has taken the lead this year also with a total production of 4,06,018 MT recording an increase of 52,605 MT from the previous year (3,53,413 MT) i.e. 14.88% and contributing about 81% of the total export oriented aquaculture production in the country. The increase in export production has occurred mainly in the shrimp species, though the production of diversified exportable species also is on the increase, albeit at a very slow pace.

Figure 1 gives a glimpse of the production trends since 2000-01 which clearly reflect the influence the Pacific white shrimp has had on the export oriented aquaculture production of the country.

Fig.1. Species-wise export oriented aquaculture production since 2000-01

 

The production trends indicated that Aquaculture production of the exotic shrimp, L. vannamei continued to replace Tiger shrimp farming in a major way despite increase in Tiger shrimp production over the previous year. Tiger shrimp registered a 11.34% increase over the previous year while scampi recorded 27% increase. Other exportable species, Crab, Seabass and Tilapia have also shown considerable increase during the years 2015-16 with their cumulative production reaching about 15900 MT (showing an increase of 335% over the previous year production of just 3650 MT).

1.1 Shrimp aquaculture production

Shrimp aquaculture production, mainly comprising of two species of shrimps (Penaeus monodon, and Litopenaeus vannamei) and one species of freshwater prawn (Macrobrachium rosenbergii) has reached 5,00,581 MT during the year 2015-16 comprising the Tiger shrimp of 81,452 MT from 68,846 ha, L vannamei of 4,06,018 MT from 59,116 ha and Scampi of 10,152 MT (majority being traditional farm of WB/ Odisha, reservoirs/village ponds of Maharashtra/ Gujarat/ Andhra Pradesh).

1.1.1. Tiger Shrimp

During the year 2015-16 the Tiger shrimp production reported was 81,452  MT, about 76% (61,998 MT)of which was reported from the West Bengal, followed by Odisha (11.28%), Andhra Pradesh (4.59%), Kerala (4.28%) and Gujarat (1.52%).  The state wise details of area utilized for culture and production during the year 2015-16 is given in table 1.

1.1.2. Pacific White Shrimp

The increasing growth trend for the Pacific White Shrimp (Litopenaeus vannamei) aquaculture is maintained during the last consecutive seven years, since its introduction into the country.  The trend has propelled the expansion of L vannamei culture in the country.  Because of the preference of this species over the Tiger shrimp during the past years, due to increased productivity, relatively disease free nature, higher yields in processing and the persistent demand and high prices in the markets, culture of Tiger shrimp is declining over the last three years in all maritime states with the exception of West Bengal and Kerala. Andhra Pradesh being the hub of scientific aquaculture, the production trends in that state reflected directly in the country’s production also.  Figure 2 gives the exponential increase in production of vannamei and the declining trend in Tiger shrimp production which reflects the trend in the country as a whole. 

 

Fig. 2.  Trend in aquaculture production of Tiger shrimp and L. Vannamei in India

L.vannamei production in 2015-16 showed an increase of 14.88%  over the preceding year. The state-wise details of area under culture and production of the species for the year 2015-16 are given in Table 4.  Andhra Pradesh once again led the table with a total production of 2,95,332 MT, followed by Tamil Nadu with a production of 44,453 MT.

1.1.3. Scampi:

Table – 7 depicts the state-wise details scampi production of all maritime states from scientific farms. In addition to the production from scientific monoculture, a production of 4727 MT of Scampi has been reported from reservoirs and village ponds. Thus the total scampi production during the year works out to 10152 MT.  Total Scampi production is reported as 10,152  MT , 27% of  increase from the previous year 2014-15, i.e. 7989 MT (Table 8), however its share in the total aquaculture production is very meagre (2.02 %).
